AutoCAD Visual LISP / AutoLISP :: Intersection Between Line And Circle
Dec 12, 2002I was looking for a post on the subject of line and circle intersections and found one that Bill Z had posted. I decided to incorperate one of the replies into my own code. In particular Luis Esquivel's code. With some minor modifications I was able to add the onseg argument that extends intersection points for the line to the circle. I also modified it to return only one point or two points depending on the line and circle supplied and the onseg argument. It seems to work great.

Nov 8, 2011I'm putting together a simple lisp routine to issue bound, purged drawings.
I have code that will do the binding & purging but need handling the saving.
This is my approach :
(1) ask the user to save the drawing using this line (command "_saveas" "" "~")
(2) run a subroutine that binds xrefs etc (this works ok)
(3) run the QSAVE command
Trouble is, if the user cancels or hits escape during the SAVEAS command the subroutine & QSAVE will still run, overwriting the current drawing. How do I handle this scenario? Or should my appoach be different?

Oct 21, 2013Can a AutoLISP command be written to read an attribute in a block and draw a circle with the attribute as the diameter using variables? The appilcation is taking the diameter of a tree trunk (the attribute), multipling by 12, and drawing the canopy circle on hundreds of those blocks. So the circles drawn will vary in size.
Not sure how this could be set up, i'm not familiar with LISP writing at all.
1) Read block, single, mulitple or definition?
2) Read Attribute
3) Varaible of attribute, (attribute is an inch measurement...it needs to be multipled by 12 to get feet for final use as circle diameter drawn)
4) Draw circle, variable, with diameter coming from attribute variable (attribute in inches that is multipled by 12)
5) Center point or circle to be block's base point

AutoCAD Visual LISP / AutoLISP :: Place Circle On Selected Blocks Insert Point?
Mar 11, 2013You have a dwg with multiple sets of different blocks and a circle you want to place on the insert point of each set blocks.
You select the circle then select one of the blocks in the set and the circle is placed on the insert point of each of the blocks in that set. It would save time from doing it manually and save on mistakes.

Feb 10, 2012I'm trying to change a routine i just wrote that draws 3d pipes. I wanted to make it so that when a user selects the beginning point and ending point of the pipe, the LISP changes the ucs to that vector, draws the circle at the beginning point and extrudes it to the second point.
It actually works great except when the ucs changes, so do my user points because of teh origin change. Is there a better way I might get this to do what I wnat it to?

AutoCAD Visual LISP / AutoLISP :: End Of One Line Is Start Of Another
Apr 24, 2013I am having a problem with starts and ends of lines. I have draw two lines, end of first is start of second. The problem is because, (cdr (assoc 11 (entget line1))) and (cdr (assoc 10 (entget line2))), somehow, are not the same,
(= (cdr (assoc 11 (entget line1))) (cdr (assoc 10 (entget line2))))
is returning nil, what is so confusing to me is that:
(=(nth 0(cdr (assoc 11 (entget line1)))) (nth 0(cdr (assoc 10 (entget line2)))))
is returning true, the same is for y and z coordinates.
I need to check x y and z coordinates, for this type of problem...
AutoCAD Visual LISP / AutoLISP :: Circles At Line End Points?
Feb 2, 2012I need to place a circle, of a user-defined radius, as a marker at the endpoints of all lines in a drawing. how to accomplish this using lisp? It doesn't matter if they overlap; I can use OVERKILL to delete those objects.
I started the code with:
(defun c:cmark ()
(setq crad (getdist "
Specify radius: "))
)
But don't know how to cycle through the objects, determine the end points of lines only.

AutoCAD Visual LISP / AutoLISP :: Delete Offset Line
Sep 6, 2013There are many lisp that draw offset line but what about opposite way , I have wall of double line i need to delete one of them let's say inside wall line .
why i need to do this usually when i tracing in external program like autocad architecture or Revit or archicad i just need outline of exterior and interior walls !.
is there way that can delete the offset line ?(or within range predefined in lisp to prevent interfering of lines deletion).
AutoCAD Visual LISP / AutoLISP :: Divide 3D Poly Line
Sep 21, 2011I have little Autolisp experience, what I need is a lisp routine that will divide a 3D Poly line to say about 1000 points and add index to the points from the start of the line to the end of the line. It is very important that the index be from the start to the end of the line, because we extract the info to excel and then use the x,y and z co-ordinate of the points on our hydraulic analysis program. We need to have the index and the x, y and z co-ordinates on our Excel sheet sorted by index and not by x, y and z.
To be more clear the 3D poly is a pipeline profile so we need to have the points in order by index and not by x, y and z.
AutoCAD Visual LISP / AutoLISP :: Control UCS Without Using Command Line?

AutoCAD Visual LISP / AutoLISP :: Unable To Draw A Line
Sep 18, 2013I've written my first little Lisp function.What it's for is drawing a simple borehole profile that can then be used to draw stylized cross sections on top of it.
Upon start the lisp, pick a point on screen (to get the X coordinate [x1 below]), then enter ground level at the command line [g1 below], then enter as many thicknesses as are present in the borehole log (will vary, but typically between 3-12). These I added to a list, because that seemed to make sense when I did it.
What I want it to do then is draw a pline from x1, g1 down to the next point (x1,g1 minus the 1st thickness), then the next (x1,g1 minus the 2nd thickness) etc., to the bottom of the borehole.
Then my CAD guys can sit there, and using the borehole logs, enter the values of the boreholes and it draws them on the screen, making it easy to join th dots.
It might be good if it placed a Acad point at each point as well, but I'm not overly bothered about that at the minute.
Here's my attempt so far.
(prompt "Type 'e1' to run...")
(defun c:e1 ( / )
(command "graphscr") (setq x1 (getpoint "
Pick insertion point:")) (setq x1a (car x1))
(initget (+ 1 2 4)) (setq g1 (getreal "
Enter ground elevation: "))
(initget (+ 1 2 2)) (setq lvllist nil ) (while (setq lvl (getreal "
Enter layer thickness <Exit>: ")) (setq lvlList (append lvllist (list lvl))) )

AutoCAD Visual LISP / AutoLISP :: Line Length Report

AutoCAD Visual LISP / AutoLISP :: Select Texts On A Line?
May 22, 2012There is a very complecated drawing. Texts are on a line and crossing a line or something like that. Some texts has insertion points on the line. When the line is selected by LISP, only the specific texts with insertion points on the line are selected. Does it make sence?
